        Simple, just shift the umbrella up or to the sides and out of the way of the blower's blast... VOILA! Thrust braking ! !

        I suspect that it's the reversal thing too thanks to the back curl of the umbrella. It may not work at all and certainly not as well if the umbrella was just a flat plate.

          Having been fooled, I'd like to know by how much. Does anybody have a leaf blower and an unpowered skateboard (or little red wagon)? How much headway, if any, can be obtained by blowing on an umbrella?

            None. Newton's third law as quoted in Wikipedia:

            The third law states that when one object exerts a force on a second object, that second object exerts a force that is equal in magnitude and opposite in direction on the first object.

              You Sir deserve a gold star, and it's why I wrote my first response so carefully, I do wish this could have played out more to separate the "who's who" in the physics department lol More later...

                  Not totally - I think we netted at least 3 --- maybe 4 lol

                    I'm waiting for Musk to put some propellers on his cars to generate energy to run the car. The faster you go, the faster the prop turns, so the faster you go. It wouldn't be 0 to 60 in 2 seconds, but it could be LA to New York non-stop.
                    I seldom do anything within the scope of logical reason and calculated cost/benefit, etc- I'm following my passion-

                      Jim --- with Darryls chime in make that 4 or 5... id call that a good day,

                      Remember when I stated in my first post "there's allot going on there" lol that was that third law of physics you cued in on,,, it's easy to see the cancellation of the two first laws,,, but bottom line is connect wind meters all around the guy and tell me which direction it's a blowin, lol

                          I tried it when i was a bored teen in 1983. The neighbor's dog had a more useful torque curve. She would also fetch a beer if you said "Molson"

                            any way you look at it - one little pothole and that guys going to bloody his pug....
                            I don't know AK, sounds to me he hooked another one.

                                While it hasn't yet been tried, it has been written about in a book written by ex-astronaut Addison 'Skip' Carmichael: The Trans-Linear Vector Principle
